LONDON, Jan 7 (Reuters) - Bond markets were given the first clues on Wednesday on how receptive investors will be to the expected glut of euro zone government borrowing this year, and the initial indications weren't encouraging.
Germany shifted only two thirds of the 6 billion of 10-year paper it put up for auction, an outcome that triggered a steep fall in Bund prices and corresponding jump in long-term yields.
Several euro zone countries including Germany again, France, Spain, Austria, The Netherlands and Ireland are all scheduled to sell bonds this week and next as governments raise funds to pay for their recession-fighting fiscal stimulus packages.
Germany's auction on Wednesday raises the prospect euro zone governments will have to pay investors higher rates of interest to take on their ballooning debt, which could result in bond issuance totalling as much as 870 billion euros this year.
"
It's a bad omen ahead of the increasing supply that's coming this year," said Everett Brown, European bond strategist at IDEAglobal in London, referring to the Bund auction.
"It's a definite worry," he added.
Even the UK auction on Wednesday of 2 billion pounds of 30-year gilts, which drew much stronger demand and was covered 1.72 times, failed to lift the price of 30-year paper or prevent a selloff of most other UK gilts.
"
Burgeoning supply everywhere ... is the main headwind for bonds this year, although it's counterbalanced by the negative economic outlook, easier monetary policy and the possibility central banks could buy bonds if yields rise too much as part of their quantitative easing strategy," Brown added.
Germany sold 4.058 billion euros of 10-year government bonds to investors, leaving the Bundesbank to take up 1.942 billion euros.
